Inventors at Stanford have developed a novel strategy to perform concurrent fluorescence measurements of multiple biological parameters in freely moving and head-restrained animals.
Fiber photometry, a measurement technique that aggregates fluorescence signal using a fiber optic, is a highly pervasive approach in the field of systems neuroscience to study in vivo brain tissue dynamics during ecologically relevant behavior.
A team of interdisciplinary researchers at Stanford have developed a small, lightweight optical strain sensor device to sensitively measure forces within the mitral valve apparatus to help determine the appropriate repair technique for patients undergoing valvular surgery for
A team of Stanford engineers have developed a fast adaptive optics system for scanning, 3D imaging and sensing with a small (50 µm) multimode fiber (MMF).
This patented technology is a magnetically actuated photonic crystal sensor system. It utilizes a photonic crystal (PC) coupled to magnetic material which is then mounted on an optical fiber.
An optical hydrophone that is insensitive to hydrostatic pressure, yet capable of measuring acoustic pressures as low as the background noise in the ocean in a broad frequency range of 1 Hz to 100 kHz is reported.
In certain embodiments, an optical device and a method of use is provided. The optical device can include a fiber Bragg grating and a narrowband optical source. The narrowband optical source can be configured to generate light.
An optical sensor includes an optical coupler configured to receive a first optical signal and to split the first optical signal into a second optical signal and a third optical signal.
